MOLD FOR THE MANUFACTURE OF BUILDING-BLOCKS.

SPECIFICATION forming part of Letters Patent No. 783,451, dated February28, 1905.

Application filed August 2'7, 1904. Serial No. 222,403.

To all whmn it may concern.-

Be it known that I, EUGENE MORENUS, a citizen of the United States,residing at Cleveland, county of Oswego, and State of New York, haveinvented certain new and useful Improvements in Molds for theManufacture of Building-Blocks, of which the following is aspecification.

This invention relates to molds for the manufacture of building-blocks,and particularly to that type illustrated, described, and claimed in acopending application filed by me simultaneously herewith and numberedserially 222,404. I

The object is to provide a novel and simple structure whereby blocks ofplastic material and having the characteristics described in theabove-mentioned application may be readily and expeditiouslymanufactured. w.

In the accompanying drawings, forming a part of this specification,Figure 1 is a perspective view of a mold constructed in accordancewiththe present invention. Fig. 2is a transverse view thereth rough. Fig. 3is a sectional view onthe line 3 3 of Fig. 2. Fig. 4 is a longitudinalview on the line 4 4 of Fig. 2. Fig. 5 is a perspective view of one ofthe side walls and the core section or member carried thereby. Fig. 6 isa vertical longitudinal sectional view through a slightly-modified formof construction-namely, one employed in manufacturing a corner-block.Fig. 7 is a cross-sectional view taken on the line 7 7 of Fig. 6. Fig. 8is a perspective view of one of the side walls and the core section ormember carried thereby of this modification, and Fig. 9 is a perspectiveview of the fillingblock employed in connection with the lastillustrated form of the invention.

Similar reference-numerals designate similar parts throughout theseveral views.

In the first illustrated form of construction a sectional body isprovided consisting of the side walls 1, having in wardly-projectingcoresections 2, which taper toward their inner ends, said inner endsabutting when the mold is assembled. As the core-sections 2 areconsiderably narrower than the side walls 1, pockets 3 are thus formedfor the reception of faces of the side walls 1.

the material that is thus molded into the spaced sections .or members ofthe block. These members or sections are connected by tie-rods 4, andthe core members constitute means for supporting the said rods while theblock-sections are being formed. The said core members are thereforeprovided in their abutting faces with coacting sockets 5, formingopenings or seats when the core members are together, which receive therods 4, the members clamping the same sufficiently to maintain them inposition. The ends of the sidewalls 1 project beyond the core members 2and have inturned flanges 6, forming, with the ends of the core members,guideways 7 that slidably receive the end walls 8.

In order that one of the block-sections may be formed with a suitableface, the end walls 8 and the side walls 1 have at their upper edgesinwardly-extending longitudinally-disposed flanges 9. A bottom 10 isadapted to be fitted against either of the open sides of the mold andextends the full length and width thereof. This bottom is detachablysecured in place by clips 11, arranged against the outer faces of theside walls and having spurs 12 embedded therein, the clips beingfurthermore provided with hooks 13, that engage over the outer face ofthe bottom. The body of the mold is held together by stirrups 14, thatextend across the ends of the mold and have terminal hooks 15, thatengage over the outer These stirrups are preferably slightly longer thanthe width of the mold in order that wedges 16 may be driven between oneof the side walls and the hooks lying thereover for the purpose ofproperly tightening the mold and preventing its accidental displacementor collapse.

In manufacturing a block the body of the mold is first placed, togetherwith the tie-rods, and clamped in the seats 5, the end wall being placedin position and the body clamped by the stirrups 14 and wedges 16. Themold is preferably placed with the lower side uppermost and theconcrete, cement, or other composition placed therein, and thus castover the projecting headed ends of the rods. The bottom is then placedupon the filled pocket and fastened in place by the clips 11, afterwhich the mold is inverted and the opposite pocket filled. After thecomposition has thoroughly set the block is removed by dismembering themold, this being easily accomplished by removing the clips 11 and thestirrups 14, whereupon the bottom is released, the side walls may bedrawn apart, and the end walls taken ofi.

The second form of mold closely approximates the above described, theonly difference being that the same is employed in the manufacture ofcorner-blocks, necessitating a slight change in the construction of thecore members and the employment of a filling-block for the purpose ofproviding a seat in the rear side of the block. The side walls are shownat 1 and have inwardly-extending tapering core members or sections 2,having seats 3, that receive the tie-rods L, the said members 2constituting clamps for holding the tie-rod in place. Pockets 5 areformed above and below the core members 2 for the reception of thematerial forming spaced block-sections. A bottom 6*is detachably securedto the lower portion of the mold by clips 7 similar to those alreadydescribed, and end walls 8 are held in guideways 9, formed at the endsof the side walls 1. Furthermore, the usual stirrups 10, extendingacross the ends of'the mold and hooked over the side walls 1, serve tohold the mold in place.

The difference in construction resides principally in the employment ofextensions 11 of the core members, which extensions are oflset at oneend of each and have coacting seats 12, that holdalongitudinally-disposed tie-rod 13. Furthermore, the ends of the coremembers 2 having the ofl'sets 11 terminate short of the adjacent endwall 8, so that one of the pockets 5 has a right-angular extension 14,the other pocket having its adjacent end spaced therefrom, as shown inFig. 6. In order that a seat may be formed in the end of the blockhaving this offset or extension, a filling-block 15 is placed upon thebottom 6. Notwithstanding these changes in the interior arrangement ofthe mold, it will be apparent that the general structure remains exactlythe same, that the core members still constitute holding means or clampsfor positioning the tie-rods and maintaining them in proper positionwhile the block is being made, and that the body of the mold issubstantially the same so far as structure is concerned and may be takenapart or placed together with facility and ease.

It is thought that the advantages will be clearly apparent to thoseskilled in the art, the same residing in the ease and expedition withwhich blocks of this character may be made, and it will also be evidentthat the invention is not limited to the exact forms and structuresshown, but may be modified in various details.

said end walls constituting the ends of thepockets and abutting againstthe ends of the core throughout thewidth of said pockets.

. 2. In a mold of the character described, displaceable side walls,core-sections carried by the side walls andhaving their inner sidesabutted, thereby bridging the space between the side walls and formingspaced pockets, said sections having substantially flat ends, anddisplaceable end walls engaging with the side walls and abutted flatagainst the ends of the core-sections throughout the width of the sameand constituting end closures for the pockets.

3. In a mold of the character described, the combination withdisplaceable side walls, of tapering core-sections carried thereby andhaving their inner sides located adjacent to each other, inturnedifianges arranged at the ends of the side walls and spaced from the endsof the core-sections forming therewith guideways, end walls slidablyfitted in the guideways, and connections between the side walls.

4. In a mold of the character described, the combination withdisplaceable side walls hav-' ing core-sections terminating short of theside edges of the mold, of end walls fitted between the side walls, abottom fitted against the lower edges of the side and end walls andspaced from the core-sections, and retainingclips secured to the sidesections and having inturned hooks that engage beneath the bottom.

5. In a mold of the character described, the combination with walls, ofa core disposed between them, a portion of said core having atie-rod-receiving seat, said seat being disposed out of intersectingrelation with the walls.
